To aZL'whom it may concern:

Be it knownthat I, Hanna: I. Tunnewou'rl-I, a citizen of the UnitedStates, residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented an Improvement in Rotary Cemcnters, ofwhich the following description, in conned t'ion with the accon'ipanyingdrawings, 1s a specification, like letters on the drawings representinglike parts. 7

My present invention is a cementing machine.particularly intended forthe use of shoe :factories and more especially for cementing such iecesas can be advantage- 5 :ously. cemented by. being folded over onthen'iselves. For example, a shoe upper has syi'nlnetrieal curves on itsopposite sides and the present way of cementingthe edge (when cementedby machine) is to hold the vork up to the cementing wheel anddexteronsly turn the work so that the cementing wheel .will followaround the curved edge in such a manner as to deliver the desired narrowstrip or layer of cement. inasmuch =-as the-curve is svnnnetrical on itsopposite sides I propose to fold the work over on itself so that the twosymmetrical curves will come. in accurate alincmentwith each other,andthen apply the content simultaneously to the opposite edges thusfolded over. My present invention is a machine for accomplishing thisresult. By this means the cen'ienting is accomplished in half the timepreviously required and-much less dexterity required on the part of theoperator'inasmuch as the application of the cement does notrreqnire-thatthe workshall be turned to any great extent, I. (2., the direction ofmove meat-is almost in a straight line as distinguish'ed from being in along-U-shaped curve as previously.

Iha'v'e given theabore illustration of cemcuting a shoe upper, tomakeclear oneof the prineipal-advantages of a. main feature of myinvention,

In carryingout the invention, I prefer ably provide, in connection withan upper cementing device and a lower cementing device, means forrendering one of these cementing devices inoperative at will or inother-words my invention includes the provision -of means for convertingthe nachinc into a one-side eementer or a two-side ceiuenter, so thatthe machine can be used for ---cemcnting on one side of the work only,

Patented Mar. 7,1911.

' whenever the nature of the work orthe preference of the user demandsthis, or it can be used for cementing on both sides of the work.

My invention also includes means for rendering it impossible for themachine to leak .or .drip cement upon the work, whatever cement may leakdown being automatic-all sucked up and returned to the cement:- tank bythe regular operation of the machine. The mounting of the cement pot ortank is also novel. means being provided whereby it centers itself sothat it putin position at all it cannot fail of being correctly placed.The regulation of the cement. is made more delicate and accurate thanheretofore by means of blocks or gates preferably of wood.

further importantfeature or sub-coin--- bination'herein claimed relatesto the provision of cushioning means or spring-giving adjustment for theopposite cement apply-' ing devices whereby the same effect onthe workis produced as heretofore with a cement applying roll made of resilientrubberlike material. and yet my roll or cement ap plying device iscomposed of metal or other unyielding substance.

The constructional details of my invention and further advantagesthereof will be pointed outin the course of the following description.reference being had to the accompanying d 'awings, in which I have showna preferred embodiment of the invention.

In the drawings, Figure 1 is a view of the machine in side elevation,parts being broken away and sectioned for clearness of illustra tion;Fig. 2 is a view thereof in end elevation, parts being similarly brokenout and sectioned; Fig. 3 is a plan view of one of the felts; Fig.4 is,a similar view of ashoe upper-in the position heretofore necessary forit to occupy when being cemented; and 1 Fig. is aplanview ofthe sameupper folded over on itself in proper position for being cemented by mymachine.

"While .my invention, in its broader aspects, is applicable to a widerange ofce mentingi, machines and appliances, it is morepart-icularlyadapted to a rotary eementer, and accordingly forconvenience of illustrw Mon and dcscriptioml'have herein shown itapplied to .the type of eementer disclosed in my Patent No. 878,959dated Feb. 11, 1908.,

Referring to. the drawings, I provide a frame comprising an overhangingarm 1,

upright or standard 2, and base 3 carrying an upper shaft 4 journaledbeneath the arm 1, and a lower shaft 5 journaled at 6, 7 in a hanger orcarrier 8 pivoted at 9 to the standard 2. The shafts 4, 5, are providedat their outer or front ends with cement delivering wheels 10, 11,having peripheral cement carry 1ng pockets 12, 13, and at their rearends wlth intermeshing driving gears 14, 15, driven in any suitablemanner, As herein shown .the shaft 4 has fast thereon a bevel gear 16meshing with a driving gear 17 fast on a vertical shaft 18 provided witha wormwheel 19 engaged by'a worm 20 on a shaft 21 provided with aspring-held clutch -22 of, any suitable kind' and operated in usualmanner by a foot lever (not shown). The

cementing wheels 10, 11,,are normally, held pressed tightly towardeachother by suitable means, which as herein shown, consists of a spring23 engaging at its rear end .a boss 24 on the standard 2 and at itsforward end held by a swiveled collar 25 adjustably supported on a handadjusted bolt 26 mounted at 27 in the carrier 8. The cement wheels maybe moved temporarily apart, and are at all times under the control ofthe operator by means ofa strap 28 connected with a treadle (not shown)and hook 29 securedin the carrier 8, an adjustable stop 30 being mountedadjacent thereto in the base 3 and provided with a thumb nut 31. forlimiting with extreme nicety the approach of one cement wheel toward or'against the other.

' The cement is delivered to the cement wheels from'any suitable source,that herein diate trough or hollow, preferably rectan-' gular, centeringcavity 37. Because of this constructiom'the tank tends automatically tocenter itself and bring itself into exactly correct position over thecement wheel simply by the act of placing it more or less carelessly inposition. As the neck 34 is placed over the arm 1 it slides naturallyinto the hollow or centering cavity 37 and is directed by the latterinto correct positiom'so that the tank is thereby brought around intoproperalinement with the wheel 10 and with the adjacent re 'ulating pad,blocks, etc. From a'practica standpointthis feature of my inventionhasprovedof decided value,

it being remembered that cement is difficult to handle, is liable tosmear and stick everything that it comes in contact with, and not easilycleaned away. The delivery opening 35 is closed by any suitable valvemecha-' nism, a rotary valve 38 being herein shown, operated by a handle39 whereby it may be opened or closed by a quarter rotation in onedirectionor the opposite. The bottom of the neck 34 is planed fiat andthe centering cavity 37 is provided withinwardl projecting flanges 4Oseparated by a sot or opening 41 for the passage of the top edge of thewheel 10, said flanges 40 serving to support in proper horizontal fiatposition a pad 42 preferably of felt, and adjacent clamping blocks 43adjusted by screws 44. This felt pad, etc.,. construction constitutes animportant feature of my invention, as it provides a construction whichnot only prevents leaks readily and is capable of quick renewal, easilyrefitted, etc., but is inexpensive, not liable to get out of order, isneat and normally out of sight. The felt padis cut out centrally andprovided with opposite beveled ends 46. The blocks 43 bear against thefelt pad lengthwise and serve to crowd the latter gently forward on allsides whenever desired, so as to engage the wheel 10 exactly as requiredaccording to the consistency or kind of ceme'ntifused. At the front endof the delivery means just below the felt I provide a small block ofwood 47,

which constitutes a gate and bears against the pocket-containing edge ofthe wheel 10, being delicately adjusted by a thumb nut 48 provided witha shoulder. 49 engaging a notch 50 in the under side of the block 47 atits outer end. I have found that a small piece of wood directly adjacentthe felt pad will produce an accuracy and nicety of cement deliverywhich it is impossible to secure by the feltalone. Instead of wood,fiber of suitable alloy or aluminum may be employed, At the same side oredge of the wheel 10 I provide a depending finger guard 51 which extendsdownwardly as close as I possible to the bight ofpthe wheels 10 and 11without interfering with the work and prevents the possibility of theoperators fingersbeingcaught by the wheel 10, while yet permitting theoperator to feed into position small fine work'which 'couldnot otherwisebe done with safety.

At the rear or up going side of the wheel 10 I have provided a featurewhich in practice has proved 'very' useful. One of the v greatestobjections to power cementer that, at unexpected moments, they-per ntmore or less cement to drop on th'ewo'rk. The present typeof;.machine'orig1nally proved no exception to this rule, and I foundthat mere scrapers would not cure the difficulty as the cement wouldflow downward near the center at .a slight distance from the axis of thewheel until it had col.- lected sufficiently to drip onto the work, butall this is doneaway with simply by em- "Qbrac-ing the rear edge of thewheel by'opposite wings 5590f a cement removing device which preferablyextend obliquely down-' ward far enough to engage the sides of the wheelat the region where the cement has been accustomed to collect. asflaboveexplained. The lower edges of these wings 52 preferably fiare slightlyas indicated at 53, the upper portions of the wings practi eallyengaging'the sides of the, wheel out, wardly to its periphery. As thewheel'rotates the cement which tends to collect in the pathv of thepoint of the cement removing device, is caught by the slightly flar inglower edge of the wings-'32 and is gradually worked outwardly'by thewings as the wheel lO continnes to rotate, until finally the cementreaches the periphery of the wheel ina globule which is held in by .aflaring guard or lip 54, with the result that the globule. of cementgradually works over, against the periphery of the wheel and iscarriedgradually upward until suddenly it sucked up, as it were, by thepockets or ..cement inthe pockets at the periphery of the wheel and thenat once. disappears up into the pocket. Preferably the part 55 of theguard or end portion of the cement remover adjacent the periphery of thewheel extends obliquely toward the periphery so as to make the throat orpassageway for the cement. gradually smaller toward the direction ofmovement of the wheel 10. In practiee this cement remover counteractsall. tendency of the machine to drip cement, and keeps the workinvariably clean.

As already stated, one of the leading and most important features ofnovelty of my present invention consists in 'n'oviding means forcementing the work at will either on one or on both sides, andaccordingly, in the preferred embodiment of my invention hereinshown, 1provide a duct from the cement tank 32 for delivering cement tothe"lower cement wheel 11, said duet being herein shownas a pipe secured bya clamp 57, anelbow 58, pipe 59. Ile. :ible tube (30, pipe (11, tubularelbow and cast1ng (i2,-the

- latterbeing provided with a shut oil valve G3 operated by a handle64;,said elbow 62 opening into a casting (35 at (36, which 1s pro-"vided. with-a-c'ement chamber 67' having: an

[opening 68 at'its top. Above the castingfii' is a casting-69 on whoseinternal ledge 70 I mount a ,felt pad 71 surromuled by movable clampingbars orplates 72, 73,,arnd held 111 place by a plate H by screws 75, theclamping plate being'm-tuatedby set screws 70., and the whole heldtogether by thumb screws 77 at the opposite ends. The wheel 11; runs .ina slot 78 of the felt pad, and a wooden block 79 bears against. the 113'oin" side of the cellular cement wheel 11 the sa me as in the case ofthe block -17 already described. The block 79 is actuated by a thumbscrew 80 whose rib 81 entersa groove 82 in said block. By this means"the utmost nicety of cement delivery or regulation is bad for the lowerside of the work at. wheel 11 as for the upper side of the work at wheel10. For "some kinds of work it is desirable to cement. the upper sideonly of the stock, and accordingly, in such case, thexcontrolling valve3 is closed and the chamber (37 is drained, being provided [or thispurpose. with a removable plug or closing device'83. And in tl1is.casethe wooden cleaner or regulator block 79 is moved back out ofengagement. with the wheel 1].

In use, let it be supposed that it. is desired to apply cement byboth'the upper and the under cement wheels on a vamp folded along" itsmiddle as shown in the drawings. both valves 38 and G3 are, opened, andthe felt pads and adjusting blocks of wood or equivalent material arecarefully adjusted so as to cause exactly the rightamount of cement'tobe delivered according to the requiremcnts of the guru piece of work,and

then the f'oot lever is operated so as to throw the driving clutch 22'-mto operation, whicl1 causes the wheels 10' a11d 11 to feed thework.ifomvard, guided by a workre s't Sjnstfat' the p rear of the meetingedges of the cement wheels. ,The result is that 'the work is quickly andneatly cemented with a thin narrow stripof cement exactly as required,and without danger of getting any cement elsewhere on the work. In casethe operator should, through carelessness, permit the work'to roll up onthe top roll or otherwise clog the machine, he letsup. on the clutch22,, which 'at once stops the machine, and then instantly depresses'thctreadle chain 28-, thereby separating the wheels 10 andll suflicientlyto permit the removal of the tangled piece of work. "The headtransmitter arrangement. of the worm and w'orm wheel giveinstantstopping and starting movement so thatthe cement wheels can runan exceedingly short-distance if desired. The spring adjustment i-----26 and the pivoting of the hanger or carrier 8 affords a yieldingconstruction which permits .the ccment wheels or' whatever cementingdevices are used to give acushion ell'cct. The result is thatthis takesthe place of the usual rubber roll, which has heretofore beenconsideredmore or less essentialfor shoe work, especially for cenldntinguppers and small work. Rubber or composition" rolls, esspecially whenused on small work such as j many of the small parts of shoes, wear outbottom wheel is'similarly adjusted.

to provide a durable substitute for the previous rubber rollconstruction. The adjust merit pfithe spring 23 permits the pressure ofthe two cement wheels to be varied as desired, and by adjusting thethumb nut 31 the normal proximity of the wheels and 11 may be regulatedwith great nicety. If 1t is not desired to cement both sides of a plece,as in the example previously given,

lo the valve 63 is closed, the stop 83 is opened,

permitting the cement to drain elf from the lower cement wheel 11, andthe wheel is run against the. block 79 and the adjacent felt pads, -etc., until it is entirely clean, where 15 upon the block 79 is moved backout of the way, and thereafter the machine is run with one cementdelivery wheel only delivering cen'ient. If at any time adili'erent kindof cement is tobe used, it is unnecessary to empty the cement pot, cleanit out, etc., as

heretofore, but instead thereof the valve 38 is simply closed and thethumb nuts 36 are caused to disengage the pot 32, which is then liftedfrom 'the machine and another similar pot containing the desired cementis put in place. It's neck 34; automaticallycenters the pot and gets itinto-exactly the right position with the flat bottom edges thereof inaccurate engagement with the felt pad 42 all around the mouth 35, thepot being clamped and its mouth brought down with exactly the rightpressure by turning up the clampingnuts 36. The wings 52 of the removercause all the surplus cement to be car- 35 ried up from the 'sides ofthe wheel 10 and back into the pot, while the finger guard 51 enablesthe operator to place even the smallest and most delicate workaccurately between the feed wheels 10-and 11. If more cement is desired,the block 47-is moved back slightly, and if less cement is desired it ismoved forward. The metal bars 43 are moved inwardly by their set screws4.4 as the felt wears or needs adjustment. then 45 the machine is usedas a double cementer,

the corresponding mechanism' adjacent the One of chief aims has been toprovide a machine capable of handling work not only quickly but so as todeliver the cement ing. line with precision and neatness, and at thesame time to use a minimum quantity of cement. i
